Texas Instruments unveiled a wireless base station system-on-chip (SoC). The TMS320TCI6616 SoC is based on The company’s new TMS320C66x digital signal processors (DSPs) and KeyStone multicore architecture, and is asserted to more than double the performance of any 3G/4G SoC in the market. It also includes a multicore DSP that processes both fixed and floating point math to simplify wireless base station software design. This SoC incorporates three elements: field proven PHY technology, an autonomous packet processing engine and programmable DSPs enabling full multicore entitlement. Implemented as configurable coprocessors, TI PHYs enable Software Defined Radio (SDR) which allows operators to rationally migrate to emerging standards without needing external components. Autonomous packet processing in the TCI6616 manages packets from both core and radio networks, offloading packet processing and freeing cycles for algorithms that enhance spectral efficiency. Together, these configurable coprocessors, which target all major wireless standards, yield the performance equivalent of over 250 DSPs, according to the company. The four C66x cores in the multicore TCI6616 provide the performance needed for custom IP implementations that base station developers rely on for product differentiation.
